Not stupid at all. Definitely yes. Don't have the numbers on hand but it's orders of magnitude more CO2-equivalent released per kg-mile, especially when you factor in the fact that they are using methane.

Of course the reality is that this tech won't ever see adoption used that widely, but where is the break-even point?

Rocket launches emit less CO2 than a trans-pacific airline flight.

> CO2-equivalent

I think what they were trying to get at is GHG emissions in general which there are more of than just CO2.
